“South Park’s” Top Ten Love Letters To Video Games
3) Imagination Land

The legendary Emmy-winning episode sees a battle of imaginary characters on both the sides of good AND evil, and video game culture is well-represented here. For the good guys, characters like Link, Mario, Pacman versus the likes of Wario, the Ghosts, and Akuma were in a battle for life and death. The trilogy episode is highly-regarded as one of the greatest South Park episodes of all-time and still holds up to this day.
"There are also other characters that come and go (also owned by the Warner Bros. Discovery conglomerate media company)."
Huh. Is that just referring to other characters from the show itself, or is this implying that the new season is going to have cameos from other WBD IPs
